You form an alliance by sending an allies add command. For example, to offer an alliance to the Privateers (player 5), write a message to yourself with this command:
allies add 5
To confirm the alliance, the Privateers must send the same command, with your race number. If you are Birds (player 3), he has to write
allies add 3
To revoke an alliance, or take back an offer, you send an allies drop command:
allies drop 5
